Both Northern Tribes and British Tribes have light cavalry at 18pts which can be fielded as skirmishers at 16pts. The northern tribes can substitute a javelin for their spear, but this option is not given for the British Tribes. Is there any reason for this, or should the British tribes light cavalry also have this option?

Do the British Tribes light cavalry need to be in skirmish formation to count as escorts?

The cavalry still count as escorts if formed, however you can only charge through them to hit an unengaged unit if they are skirmishing. British Tribed light cavalry should be able to substitute javelins for spear and I will issue an errata for this.
